Since the Federal Garden Show in 1979, the Rheinaue leisure park has been Bonn's "Central Park". On a stroll through the 160-hectare recreational area, you will discover the special features, background and the comprehensive significance of the entire area and the adjoining area with the Post Tower and the United Nations Climate Secretariat. The Rheinauensee lake, the nature trail of annual trees, the rose garden and the garden for the blind are just a few examples of the diversity of Bonn's Rheinauenpark. At least 30 percent of the tour guide's fee is donated to the Haus der Natur support association
